Then it happened. My Charcoal......the fire........everything BURNT OUT on the lava island on the center while trying to tame two of these. Then I added in Charcoal to their slots because my weight was full. I came back........all the Charcoal was gone. THEY EAT CHARCOAL GUYS! ITS NOT TOO EFFECTIVE, BUT THEY EAT CHARCOAL!
Easiest and safest way to tame this is to lure it under water. They stop aggro and you can tame as you please. Just make sure you come up for air every once in a while. Also be sure the water is deep enough.
